From the Worst Previews website today:
"National Treasure" hit theaters back in 2004 and went on to gross $348 million worldwide on a budget of $100 million. Considering the budget, the film wasn't considered a huge hit, but a sequel was greenlit. That sequel was released three years later and grossed a whopping $457 million.
Clearly there's a fan-base for this franchise, but has yet to move forward with a third installment. Now that director Jon Turtletaub is promoting his "Last Vegas" film, Collider asked why we have yet to see "National Treasure 3."
"It's so damn hard to write a great historical mystery based on fact," he replied. "We want to do the movie.Disneywants to do the movie. We're just having the damnedest time it."
Turtletaub continued: "I'd say we're about half-way there. It's not onlywritinga great historical mystery, but we've gotta write something that has nothing to do with anything we've done before. We really want to make sure that the third one doesn't just feel like a repeat of the first one."
When asked if he believes "National Treasure 3" will ever happen, he replied "I do. I'll bet that within two years, we'll be shooting that movie."
